ROLL EDGE FOR MATTRESSES OR CUSHIONS Filed Feb. 24, 1931 Lil Patented June 28, 1932 UNITED STATES PATENT OFFICE ROMAN KORNEY, OF CHICAGO, ILLINOIS, ASSIGNOB. OF ONE-HALF TO THE ROME COM- PANY, INCL, ACOBPORATION OF NEW YORK ROLL EDGE FOB MATTRESSES 0R CUSHIONS Application filed February 24, 1931. Serial No. 517,689.

It is common to provide mattresses with sausage-like formations extending around the same at the top and bottom, such mattresses being said to be of the roll-edge type. In order to produce these roll-edges, the mat tress is stitched diagonally through the side and top and bottom walls, at some distance from the corners; drawing the corner portions of the covering or sheathing into a more or less tubular form about an enclosed mass of padding. The stitches are large and composed of comparatively heavy cords, with the result that an uneven appearance is presented along the, lines where the stitches pass through the sheathing.

The object of the present invention is to provide simple and novel means whereby the unevenness of the roll-edge, produced by the diagonal stitching, is effectively concealed and the edge rolls meet the body portions of the sides and the top of the sheathing or covering along lines that are straight along the sides and the ends and smoothly curved at the corners, if the corners of the mattress are curved.

In carrying out my invention, I produce the mattress or cushion in the usual way, excepting that the meeting edges of the sides and top and bottom sheets need not be bound. Either before or after the sheathing or the covering is applied, preferably before, I sew to the side and top and bottom sheets, along lines that will lie just outwardly from the lines of stitching in making the edge rolls, fabric strips that will serve as sheathings for the edge rolls. After an edge roll has been made, the adjacent strips on the side wall of the covering and the corresponding broad face of the mattress are swung out over the edge roll and their free marginal portions are joined and bound with tape, if desired. Since the strips are secured to the mattress covering by ordinary close stitching, they cause the edge rolls to merge into the body portions of the covering along smooth lines; thereby concealing the unevenness of the edge rolls proper, or primary edge rolls, due to the coarse diagonal stitches, because the primary edge rolls in the finished product simply constitute cores enclosed in neat, attractive sheathings or casings.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for a full understanding top sheet and 2 the side or edge sheet of a mattress or cushion covering; and 3 is the filling for the mattress or cushion. An edge roll is formed by coarse diagonal stitches 4, across the corner between the sheets or walls 1 and 2. This is all old and well known, and may be said to be simply illustrative of ordinary mattress construction. The fabric of the covering in the edge roll area is in two layers, the inner layer being employed in the usual way as part of the covering and the .r

outer layer serving as a sheathing for the edge roll. The extra layer is obtained by sewing long strips to the covering proper along lines near those at which the stitching l enters and leaves the fabric. rangement shown, the strips, which are indicated at 5 and 6, lie on the outside of the main covering and are secured thereto by stitches 7 and 8 that are concealed when these strips or wings are swung or folded over '1 upon the edge roll portions 9 and 10 of the main covering;

When the mattress is made up in'the usual way, the wings or strips are left free, as shown in Fig. 2. These wings or strips are then swung toward each other so as to overlie the sections 9 and 10 of the main covering and form a sheathing over the edge roll. The meeting marginal portions of the wings or strips 5 and 6 are fastened together, con- In the arveniently by stitches 11 through the same and a suitable binding tape 12, as indicated in Fig. 3. The sheathing layers are preferably drawn taut before being sewed together, so that they will fit snugly over the edge roll.

In the completed product, the coarse stitches 4- are concealed behind the sheathing, as are also the Wave-like distortions of the mattress or cushion, due to the pull exerted by the coarse stitches 4 at widely separated points in producing and maintaining the initial edge roll. The sheathing, however, joins the main covering along smooth, even lines and so, also, must the finished edge roll.

While I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the definitions of my invention constituting the appended claims.

I claim:

1. In a mattress or cushion, two meeting flexible walls extending at an angle to each other, padding in the angle between said walls, the marginal portion of each wall being in two layers secured together at a considerable distance from the edge of the wall, the meeting edges of the under or inner layers being connected, diagonal stitches through only the under or inner layers and the padding forming an edge roll, and the outer or upper layers covering the said stitches enclosing the edge roll and being secured together at their free edges.

2. The combination with a mattress or cushion, includin a covering and an edge roll defined by rows of stitching, of two strips or wings secured to the covering on opposite sides of and adjacent to the edge roll,

and inwardly from said stitching, said strips or wings extending outwardly across the stitching to the corner of the mattress or cushion and means connecting said wings to form a casing or sheathing for the edge roll.

3. The combination with a mattress or cushion, including a covering and an edge roll produced by coarse diagonal stitching, of a sheathing enclosing said edge roll and extending inwardly from the corner of the mattress or cushion across and concealing the stitching, and means securing the inner edges of the sheathing to the cover.

In testimony whereof, I sign this specification.

ROMAN KORNEY.
